 Okay, so let's do another one of these reactions. This one says again complete the following reaction and write the major products for these ones Hopefully you can tell this is well remember there's only two reactions for an alkane One was the radical which we just did the other ones the combustion It's a combustion reaction Remember whenever you have a combustion reaction of an alkane the products are always going to be what? carbon dioxide and water Okay, so if you forget that Then you're not going to be able to do this problem Okay, so What they're really asking for these types of problems these combustion reactions is to for you to balance the reaction That's really what they're doing. Okay, so we look at this molecule here. What is the molecular form? then C4 So we got C4Ug O2 CO2 H2O So we've got we're going to remember how to balance equations. Now. It's just effectively balancing equation, right? C H O So we've got four four and two like that, right? So over here C H and O we've got one two and three Okay, so four one so we're gonna have to do multiply that by four Right, so when we do that we get four of those, okay? So when we put four of those right four Eight, right? How many do we have to do? So now how many oxygens do we have over here so four Two times four is eight plus four is twelve, right? So Three is this It's a twelve. Okay over here. We have two so what do we got to do? I Like that and that's going to give us well, right So we put a six there We don't have to put anything there, right because it's understood to be one So this is your balance chemical equation is one cycle of butane Plus six oxygen molecules goes to four carbon dioxide molecules plus four water molecules Any questions on this one? No questions. Okay, so just to make sure you remember how to balance these combustion reactions, okay? I know they're a little difficult, you know, but
